Osaka Dojimahama Tower / Redevelopment of Dojima Park / Dojimahama Pier

A panoramic view from the Dojima River. The riverside disaster prevention dock was the first of its kind in Osaka Prefecture and was built by a private company. By using a floating pontoon that is not affected by fluctuations in weather, it has greatly contributed to improving the city's disaster prevention capabilities and promoting tourism.

Osaka Dojimahama Tower / Redevelopment of Dojima Park / Dojimahama Pier

This project is a reconstruction of the Osaka Mitsubishi Building, a symbol of the region (completed in 1969). Taking advantage of its iconic location where Midosuji, the hub of business and transportation, intersects with the Dojima River, the hub of culture and administration, this large-scale complex is themed around promoting exchanges between business, tourism, and local areas, and between government and the private sector.
The lower floors will house offices, the upper floors will house a hotel, and the middle floors will house tourist facilities for public relations and corporate events. By combining these functions that extend into the local area, the entire building was intended to be "a theater-like space where you can experience the charm of Osaka from the front row." The adjacent Dojima Park and tourist boat dock will also be integrated, enhancing the symbolism of "Aqua City Osaka" and contributing to strengthening the area's disaster prevention capabilities through water infrastructure.

Dojima Park Redevelopment / Dojimahama Pier

This project redeveloped Dojima Park, which faces the Dojima River on Midosuji, Osaka's main street. The park facilities have been arranged in a three-dimensional manner to enhance hydrophilicity, and the park is linked to the "Osaka Tourist Toilet Kawamo" and government-owned smoking areas that will be installed within the park, improving urban amenities.
The aim was to create a new, lively waterfront space by developing the area in an integrated manner with Dojimahama Pier, which connects to Dojima Park, and the adjacent Osaka Dojimahama Tower.
